There are matchups that intrigue, and then there are collisions between champions from different disciplines that promise to answer questions fans have debated for years.
On Friday, March 13, 2026, inside Lumpinee Stadium in Bangkok, Allycia Hellen Rodrigues will stake her ONE Women’s Atomweight Muay Thai World Championship against Phetjeeja, the reigning kickboxing queen at the weight, in a champion-versus-champion showdown that headlines ONE Fight Night 41 on Prime Video.
The date carries its own superstition, but neither fighter built her career by believing in luck over preparation.
Rodrigues enters riding tremendous momentum — three consecutive victories since her lone promotional setback in September 2023. The 27-year-old Brazilian mom-champ captured gold by unseating Stamp Fairtex in her promotional debut back in August 2020, then took an extended hiatus for the birth of her first child before returning in March 2023 to unify the championship against interim titleholder Janet “JT” Todd, becoming the division’s undisputed queen.
Her most recent defense showcased the power that makes her dangerous — a third-round knockout of Sweden’s Johanna Persson at ONE Fight Night 33 last July that earned a $50,000 performance bonus. That stunning finish came five months after she stopped Ireland’s Marie McManamon via fourth-round technical knockout, building a case that her time away from competition hadn’t diminished her championship capabilities.
The Phuket Fight Club representative now faces her toughest challenge against an absolute phenom.
Phetjeeja arrives carrying a perfect 8-0 promotional record and the ONE Women’s Atomweight Kickboxing World Championship. The 24-year-old Thai striker from Team Mehdi Zatout defeated legendary striker Anissa “C18” Meksen for the interim title in December 2023 before unifying the gold against Todd three months later, establishing herself as the division’s kickboxing queen.
“The Queen” recently returned to her Muay Thai roots at ONE Fight Night 38 last December, demolishing Poland’s Martyna Dominczak via first-round technical knockout in a performance that showcased why she remains one of the organization’s most feared competitors across multiple disciplines.
Her remarkable journey began at age 7, training at Or Mee Khun gym — built by her father when no other facilities would train females. By age 10, she had compiled over 100 fights, 70 against boys, earning the nickname “The Girl Who Could Defeat Boys” before becoming WMC Muay Thai World Champion at just 14 years old.
The matchup pits Rodrigues’ World Championship experience and power against Phetjeeja’s striking perfection and elite technical skills. The Brazilian brings the kind of finishing ability that has produced knockouts in her recent defenses. The Thai brings an undefeated promotional record and technical mastery honed through a childhood spent fighting opponents who didn’t care about her gender, only whether she could match their violence.
Champion versus champion carries its own mathematics. One leaves with both belts intact, the other departs having learned that dominance in one discipline doesn’t guarantee supremacy when the rules change. Rodrigues defends her Muay Thai throne against a kickboxing queen returning to the art that forged her. Phetjeeja seeks to prove her recent Muay Thai knockout wasn’t aberration but statement.
